焦化苯精制生产工艺改造

Renovation of Coking Benzene Refining Production Process

苯在工业生产中用途广泛,其主要来源于焦化苯的精制。文章通过对原15万t润滑油加氢装置的工艺内容改造、设备改造、土建改造、自控改造和电气改造,达到将粗苯中硫化物如噻吩等物质脱除的目的,精制成的合成苯满足工业使用要求。

Benzene is widely used in industrial production,mainly derived from the refining of coking benzene.The paper aimed to achieve the goal of removing sulfides such as thiophene from crude benzene by modifying the process content,equipment,civil engineering,self-control,and electrical aspects of the original 150000 ton lubricating oil hydrogenation unit.The refined synthetic benzene met industrial usage requirements.
